serve to explain Figure 1 is a plan view illustrating a completed wheel in accordance with the present invention. Figure 2 is av section taken .on the line '22 of Figure 1 and Figures 3 to 6 are diagrammatic sectional views illustrating several steps in the method of the present invention as applied to the make ing of wheels.

The present invention has for its object the provision of a novel and imp roved method of making small wooden wheels for toys and other disc like objects.

A further object is the provision of an extremely simple and economical method of producing small ornamental discs, such as wheels for toys, which will be very attractive in their appearance and will be durable a method of forming Still another object is the provision of wheels for small toys which will run true and will have little friction.

In accordance with ner of carrying out invention, a wheel which may present ors, is provided with for small a hard, we

the present preferred manthe method of the present toys is produced areas of three different colar resisting tread,

an accurately formed axial hole, and a narrow,

low-friction bearing non-rotating part of the toy wheel is used.

It will be understood that surface to contact with a with which the the foregoing general description and the following detailed description as well are exemplary and explanatory of the invention but are not restrictive thereof.

(01. 4124) deformable material, having an axial hole ll formed by Dunchingthe disc, said disc being radially; compressedi'and axially embossed in the direction, of; the grain of the wood. On its outer side, the disc is.preferablyqprovided with an 5 ornamental embossed design, comprising relief portion l2 and intagliatedportions !3, while on its inner side it is preferably provided with a narrow annular portion I4, formed by embossing, adapted tobear against a stationary portion of 10 the toy and insure easy rotation of the wheel. The wheels or other ornamental discs of the present invention, are preferably formed from axially-grained discs of wood which have had their surfaces impregnated with a dye of a color 1 contrasting-with that of the natural wood, this impregnation not, being carried out sufliciently long to penetrate deeply into the body of the disc. As the discs are embossed, the intagliated portions l3 thereof are separated from the raised 20 portions I2 by a narrow axially'extending por 'tion I 5 of natural wood, contrasting with the color of the remainder of the disc. After the raised portions of the disc have been painted, as by of the embossed portions by moisture and there- 30 by destroying the appearance of the wheels, but also protects the dye from. being dissolved if a child puts the wheels in his mouth and further, serves to lubricate the ring Hi to reduce the friction of the wheels.

Figures 3 to 6 of the drawing illustrate diagrammatically the successive steps in the embosing and punching of the discs. As there shown, the blank discs 20, preferably of wood with the grain extending axially of the disc, and 4,0 slightly larger in diameter and thickness than the required dimensions of the finished wheels, are fed one by one into position over the lower embossing die 2 I, which is provided with a flared or bell-mouth. The discs are supported over the 45 die by means of a sleeve 22, at the peripheral edge of the disc, which supports the disc parallel to the face of the lower die. After the discs have been fed to the position shown in Figure 3, the upper die 23 is lowered against the disc and 50 forces it into the sleeve member 24 through the bell mouth 25 thereof. This produces a powerful radial compression of the disc and serves to densify the wood, rendering its peripheral surface considerably harder than the natural wood 55 boss the flat faces of the disc.

terial, punching a and absolutely true. as the upper die 23 Figure 4, finally assumes a position flush with the upper surface of the lower die. The two dies are thus forced towards each other to deeply em- Due to the relatively sharp edges of the raised portions 26 of the die faces, the surface of the disc is broken and, the relief and intagliated portions of the embossed flat faces are separated from each other by a narrow strip l5 of undyed wood.

After the upper and lower dies have assumed their position of maximum compression, the punch plunger 21, reciprocable in die 2|, is raised and pierces the disc to form thecentral; axial hole therein. The punch plunger, after piercing the disc, enters a cooperating hole 28 in the up.- per die and discharges the punched out piece 29 into said hole. The punch plunger is then Withdrawn leaving the punched out piece in the flared upper part of the aperture 28,- the upper die 23 is restored to its original position, andsleeve 22 is'raised to its original position where the embossed wheel I is displaced by the 'feeding-in movement of a new unembossed disc 20. Due to thefact that the disc is punched while under Sleeve 22 is then lowered powerful radial compression; and the punching plunger 22 is unsupported for only a short dis-' tance, the axial hole may be formed with extreme accuracy, both as to size, centering and direction, thereby-producing a wheel greatly superior to any produced by drilling.

After this embossing operation, the raised portion l2 may, if desired, be pointed tofurther ornament them. 7 p U 1 r The invention in its broader aspects is not 'limited tothe specific mechanisms shown and describedbut departures may be made therefrom within. the scope of the accompanying claims without departing from'the principles of the in-i vention and without sacrificing its chief advantages. r

What I claim is:-

1. The process of ma wheels by embossing compressing an oversize disc of deformable mahole in the center of the disc and axially embossing the disc.

ufaoturing ornamental descends, and, as shown in which includes radially 2. The process of manufacturing ornamental discs by embossing which includes radially compressing an oversize disc, punching a hole in the disc while under radial compression, axially embossing the disc, withdrawing thepunch and releasing'the pressure on the disc. 7

3. The process of manufacturing ornamental discs by embossing which includes radially compresing an oversize disc of wood which has been previously surface waxed and colored, punching an axial hole in said disc while under radial compression, axially embossing the disc and coating the raised portions of the embossing with paint. 7

4. The process of manufacturing ornamental discs by embossing which includes radially and axially compressing an oversize disc to densify the material and ornament its flat surfaces and punching an axial hole in said disc while it is radially compressed.

5. The process of manufacturing ornamental 'wheels by embossing which includes impregnating the surface only of a disc of wood with dye of color contrasting to that of the Wood, and deeply axially embossing the disc to provide light edges separating the raised portions of the embossing from the compressed portions.

6. The process of manufacturing ornamental wheels by .embossingwhich includes impregnating the surface only of a disc of wood with dye of a color contrasting with that of the wood, deeply axially embossing the disc to provide light edges separating the' raised portions of the embossing from the compressed portions and painting the raised portions with a third color.

'7; The process of manufacturing ornamental wheels by embossing which includes impregnating the surface only of a disc'of wood with dye of a color'contrastin'g' with that of the wood radially andaxially compressing thedisc and punching an axial hole therein while under radial compression, the axial compression being sufficiently deep to formareas of natural wood color between the high and low portions of the compressed disc and painting the high portions with a third color.
